cast was scoped to the steady state: manifest → Coolify, forever. It had no
adoption path — no way to bootstrap the age store from an instance built by
hand, before any manifest existed. The operator did it by hand: curl the envs,
assemble 17 name=value pairs into /dev/shm/prod.env, age -r, shred. Every input
to that pipeline is something cast already has, so a human was shuffling cast's
own inputs through a terminal, with the leak (scrollback, history, a tmp file
that never got shredded) and the silent miss both live.
cast capture <org>/<repo> --env <env> [--generated N] [--override N] [--force]
The required set comes from the MANIFEST, not the box: the ${...} refs in that
environment's env templates, read by the same parser apply uses to demand them.
resolveTemplate and templateRefs now share one grammar — a drift between them
would mean capture collects a different set than apply later requires, which is
exactly the "a name silently missed" failure this verb exists to remove.
The mapping is deliberately NOT mechanical. A DATABASE_URL read off the source
points at the SOURCE box's Postgres: confidently wrong, entirely plausible, and
the target's real URL does not exist until Coolify creates the resource. So the
manifest declares `generated_secrets:` and those names are written as the
literal `pending-coolify-generated`. staging's ADMIN_EMAIL must be the operator,
not the source's — staging and prod share a Mailgun domain, so a staging box
carrying the real address can mail real users; that is --override.
A "capture everything" verb would be wrong in ~4 of 17 entries, silently —
worse than being wrong in all of them. So every name is forced into a
disposition, and two of the four stop the run: a name required by a template but
absent from the source REFUSES (an empty substitutes to nothing and the app
boots misconfigured), as does one name carrying different values on two
resources.
generated_secrets is a manifest property rather than a flag the operator must
remember, because the manifest is what knows DATABASE_URL comes from a database
it declares. An entry no template refers to is a hard error: a guard standing
over nothing reads like a guard, and the likeliest cause is a typo whose real
name is then captured from the source instead of placeheld.
Secret hygiene, all covered by tests asserting on real values:
- the plan prints names and provenance, NEVER values
- an --override's value comes from $CAST_CAPTURE_<NAME>, never argv (`ps`)
- plaintext is piped to age on stdin — never a temp file, stdout, or history
- an existing store is not overwritten without --force: it may hold the only
copy of values the source no longer has (apply's never-delete, applied here)
capture inherits diff's absent-target refusal (D-237) — against a project that
isn't there it would report every secret as missing, an alarming report about
the wrong box — plus the team assert and the --path/--env prod ban. The last
gate is a typed confirmation of the environment's name; there is no --yes.
The end-to-end test decrypts the store cast wrote and asserts on its contents,
so "exactly the names the manifest requires, no more and no fewer" is checked
against real ciphertext rather than against cast's own console output.
